* Taint kernel after WARN_ON(condition)Nur Hussein2008-04-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The kernel is sent to tainted within the warn_on_slowpath() function, and whenever a warning occurs the new taint flag 'W' is set. This is useful to know if a warning occurred before a BUG by preserving the warning as a flag in the taint state. This does not work on architectures where WARN_ON has its own definition. These archs are: 1. s390 2. superh 3. avr32 4. parisc The maintainers of these architectures have been added in the Cc: list in this email to alert them to the situation. The documentation in oops-tracing.txt has been updated to include the new flag.

* Report that kernel is tainted if there was an OOPSPavel Emelianov2007-07-17
| | | | | | | | | | | | | | If the kernel OOPSed or BUGed then it probably should be considered as tainted. Thus, all subsequent OOPSes and SysRq dumps will report the tainted kernel. This saves a lot of time explaining oddities in the calltraces.

* doc/oops-tracing: add Code: decode infoRandy Dunlap2007-07-16
| | | | | | | | | | | | | Add info that the Code: bytes line contains <xy> or (wxyz) in some architecture oops reports and what that means. Add a script by Andi Kleen that reads the Code: line from an Oops report file and generates assembly code from the hex bytes.

| | | | | | | | | | Kdump has been merged and supported on several architectures. It is better to encourage to use kdump rather than non standard kernel crash dump patches.

* Linux-2.6.12-rc2Linus Torvalds2005-04-16
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
